During this time, the mean adult 7° Sr body bur- den rose to 78 Bq while the mean adult 1370, body burden rose to 78 kBq. Follow- ing the departure of the residents from Bikini Atoll, body burden measurements were conducted in January and May 1979 and August 1980 to determine the elimination rate of 13765 and 905, for the Marshallese copulation. Using these data, the dose equivalents during and post the residence period on Bixini aAteli (committed dose equivalent) have been calculated. The mean adult total dody dose equivalent from internal and external sources of radiation was approximately 10 mSv (1000 mRem). The mean adult total body committed dose equivalent was 11 mSv (1100 mRem). INTRODUCTION Bikini Atoll was one area used by the U.S. government to test nuciear weapons from 1946 to 1958. Prior to commencement of the testing prcegram, ail
